Desalination Pre-Treatment System
Middle East
The desalination plant required a pre-treatment system handling 50,000 m³/day of seawater with heavy biofouling. Aggressive chlorination (up to 5 ppm NaOCl) and acid dosing (HCl to pH 6.5) meant all wetted components needed exceptional chemical resistance in a marine coastal environment.
Jasmino designed and delivered 12 FRP filtration vessels with internal rubber lining, three chemical dosing skid packages, and interconnecting piping — all engineered as an integrated pre-treatment module.
Our approach
Process Design
Hydraulic modelling of the three-stage filtration train — coarse screening, multimedia filtration, and cartridge filtration. Optimised backwash sequencing to minimise water loss.
FRP Fabrication
12 filament-wound FRP vessels rated for 6 bar operating pressure. Internal surface prepared and lined with natural rubber for seawater and chlorine resistance.
Dosing Systems
Three skid-mounted dosing packages — NaOCl, HCl, and coagulant — with FRP day tanks, metering pumps, and PLC-controlled dosing logic.
Installation Support
Full supervision of mechanical installation, piping tie-ins, and pre-commissioning flushing. System handed over with 99.2% availability in first 30 days.
